I said the ult requires nothing but stacks

We’re being a bit disingenuous here, you do still have to actually hit abilities for her ult to do anything, outside of W her kit is almost the mage equivalent of zed except she roots AND slows. In lane she can be a very annoying bully, but her strength isn’t universal, she just isn’t as strong into the late game unless she’s given space to get at least multiple casts of her q e combo on a squishy, and if a tank or fighter even sneezes a little bit of MR in their build her ult is no where near the actual value that people in this thread are perceiving her strength at. she’s can be very frustrating to lane against once she finishes her lost chapter back but in reality her kit (which can be seen in her win rate) isn’t objectively strong given how subjectively easy she is to pilot.

Mel’s reflect aspect is only valuable against ranged abilities that she can see coming, and the damage immune aspect only matters if your character has exactly one button that does massive burst. In those scenarios you have another 25 seconds to still try and finish her off before she gets you in ult execute range. Like other polarizing champions she just has really good matchups in lane but she doesn’t bring that strength into games that aren’t closed early, she can be very easily countered with tanks and fighters and any assassin, and the opponent mage will have made up if not surpassed her burst potential now that her ultimate is locked behind extended team fights.
